OIL BURNER.

Application led January 28, 1928.

This invention relates to an oil burner for use in buruino' a mixture of oil and steam, one of the objects being to provide a novel form of nozzle the parts of which are easily separated for the purpose of making adjustments or repairs and for cleaning.

Another object is to provide a simple and compact structure having means'for effectively atomizing the fuel before it leaves the nozzle, there being a fuel controlling element which is renewable and replaceable for the purpose of varying the proportion of oil and steam.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangenient of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings,

Figure 1 is a central longitudinal section through the burner.

Figure 2 is a section on line 2 2, Figure l.

Figure 3 is an end elevation.

Figure a is a detail view of the dividing plate.

Referring to the figures by characters of reference l aud 2 designate blocks which are of duplicate construction and disposed oppositely to each other. Fach of these blocks has a. bore 3 extending thereinto from its back end, the rear portion of the bore being counterbored as at 4 while the front end is extended at right angles to provide an outlet 5 opening through the inner face of the block. A recess G which is preferably fan shaped, is formed in the inner face 7 of each block, the outlet 5 of the bore being located to deliver into the back portion of this recess.

interposed between the blocks 1 and 2 are spacing plates S and a dividing plate 9. Each of the spacing plates is formed with a slot 1() the inner end portion of which communicates with one of the out-lets 5. These slots are fiared forwardly toward their outer or front ends as shown particularly in Figure 2. The dividing plate 9 is interposed between the spacing plates 8 and terminates at its forward end inwardly from the forward ends Serial No. 250,212.

of the blocks 1 and 2 thereby to provide a small atomizing or mixing recess 11 wit-hin the outer portions of the slots 10 and in front of the dividing plate 9. The front portion of the dividing plate has its edge bevelled as shown at l2 so as to form a fine edge. An oil supply pipe 13 opens into the counterbore 4 in block 1 and a steam supply pipe 14 opens into the corresponding counterbore in the block 2.

The blocks and the interposed plates 8 and 9 are held together by screws 15 extending therethrough and serving to bind the parts together tightly.

lu practice the several parts are assembled, it being understood that the slots 1() in the respective plates 8 are to be of such size as to insure the mixing of oil and steam in predetermined proportions. By referring to Figure 2 it will be seen that the slot 10 in the steam controlling plate 8 is wider than the slot in the oil controlling plate. Thus the volume of steam admitted to the mixing recess 1l will be greater than the volume of oil admitted to said recess. Should other proportions be found desirable, other plates 8 having larger or smaller slots can be utilized.

Vhen the steam issues from the block 2 and the slot 10 communicating therewith it will mix with and break up the oil iowing from the block 1 into the slot l() communieating therewith. The mixing of the two tiuids will take place in the recess 11 along and beyond the edge 12, a thorough atomizing of the oil being effected so that maxinnnn eiiiciency will result.

By providing the recesses 6 the tiuids can iow more freely into the slots 10 than would otherwise be possible.

lVhat is claimed is:

A burner including opposed blocks of duplicate construction, each block having a bore therein opening through one face to provide an outlet for fuel, said blocks being oppositely disposed with their outlets opening toward each other and in alinement, spacing plates between the blocks each having a slot extending therethrough registering at its inner end with the adjacent outlet and gradually increasing in width to its outer end, the slots in the respective spacing plates being of diderent areas, a dividing plate interposed between the spacing plates and bridging the slots, said dividing plate terminating between the slots at a point inwardly from the adjacent edges of the blocks and having said inwardly termination portion beveled along its edge, Said bevel eX- tending laterally beyond the slots, there being a recess in each block extending partly around the adjacent outlet and across the adjacent slet, and means extending through the blocks and plates for holding them together.

`:[n testimony that I Claim the foregoing as my own, I have hereto affixed my signature.
